J parts of a ledge Be it known that l, FELIX SCHAETZKE, a

- subject of the German Emperor, and a resident of Bohum, Germany, have invented certain new and useful improvements in lWindow Sashes and Tighteners, of which the following is a speci'lication. Y

' The present invention has for its object to do away with the slidingrooves usually arranged. the sides o sash-windows by securing and tightenihg-the sashes in their closing position by means of a displacement oi the sashes themselves eliected by means of astened to the'oasement or sash-trame which' bring about a displacement of the sashes during the slide, a slanting l siideinstead of a vertical slide, whereby the sashes are brought before a tightening-ledge e i which covers the cletts or ehm s.-

Fig. 1 shows a longisash-window Fig. 2, a longitudinal secti on through the upper sash and a side `View of the lower sash. Fig. 3 shows a cross-section on the broken line :t of Fig. 1; Fig. 4, a cross-section on the broken line y y of Fig. l, .and Fig. 5 a lon itudinal section through the lower part of t e lower sash turned into the room and in a slanting position.

. struction..

The two sashes ay and I), which are in Fig. 1 oi the drawings shown in their closed position,

be seen, no lateral guidingpms; but their planks are quite smooth and there is sulicientspace between them and the sash-frame c that in their up-and-down movement they do not come in contact with the frame. 'The .tightening of both sashes is effected 'by a projecting ledge e, provided on the sashorame, against which the sashcs are pressed during their slide and shortly before they reach the closing position by the arrangement that the cross-bar of the upper` sash a is provided with a slid ing-ledge f, which l'its into a wedgeshaped groove oilthe'case- If the sash a is raised, of the'said wedgeeach other and produce a slantingslide-in other words, a pressure of the wholesash againstvthe tighteningbut in order that on pushing up the the slanting surfaces sash (L the entrance of the slidingedge ff A be turned till it'strikes into the groove f2 of the sash-framec-in other words, "a sliding on each other. of the slanting surfaces of the partsff-may be facilitated the edge a of theframe of the window-sash may be rounded at the top and a slidingledge d, preferably of the shape shown in Fig. l, but which may also be of the shape shown in Fig. 2, with a slant at the bottom, be provided von the sash-frame c, Fig. 2, on whose slanting edge the rounded edge a glides Ver easily, so that it is very easyto move the sas a," but instead of this, as shown in Fig. l, a longitudinal ledge t may be arranged on the easement c, extending down tothe laower edge of the upper sash, which ledge may be easily fixed by means of screws, in which case the sash is pressed against the ledge e by elastic springst, arranged between the ledge and the sash. The same sliding arrangements be tween the sash and the casement'may also be made for the lower sash l), the means used there, however, for attaining a good tightening, and shown in the drawings, are slightly different, though on the same principle. lnstead oi between the cross-bars the sliding arrangements may also be arhxed to the sides. Thus, for instance, on the front side of the lower sash b there is arranged on either side a glide-roller 7c, restingon a slanting surface or track formed by a ledge m m at the side of the easement. Also by this arrangement there is effected a slanting slide and engagey ment of the tightening-grooves provided on the weather-board n or on the lower crossbeam of the sash b, which brings about a pres 9o sure or" the same against the ledge e. The same effect is produced in the middle of the window by the lock-bolt o, so that the window is tightly closed all around.

'If the loclebolt o, which unites the eross- 95 ledge of the frame of the sash b with the upper sash o, is opened, the lower sash l), whose Cord w does not extend down to the bottom, but is fastened a't t to a ilat iron slat o, fastened to the sashframe, can be turned into the room in the `direction of the arrow o. Such a position "of the'sash l), in which it is turned in to the room, is shown in Fig. 5, from. which it can be seen that the sash has its supporting-point at y'. As the turning into the room of the sash b is checked by the ledge m m, which projects into its tracker way, but which vcan be turned sidewise on the hinge-joints m2, the sash can of course only against the ledge m in IOO i it, it is necessary to remove, besides the le ge fm, m', e third ledge u, which maybe of the seme breadth as the leii e 'm sndwhich, es shown" inligs. 1 sind 2, l1 rewise revents .the sash .iroin bein '-iturnetl.rntol't-roein.
